A tag hanger has a strap which can pass around a support structure, such as a D-ring on an animal collar, and a retainer assembly that clamps one or more tags to one end of the strap, restraining their motion to prevent noise caused by the tags jangling together. The other end of the strap attaches to the retainer assembly to secure the tag holder to the support structure. A blocking element can be included on the strap to prevent contact between the tags and the support structure. The retainer assembly can employ a hex-head bolt that serves as a base element and a threaded retainer shaft that passes through a retainer passage in the strap and through hanger passages in the tags a nut threadably engaging the bolt can then serve as a clamping element to secure the tags to the strap.
